I'd like to be able to walk 30 min and start fishing where no one else is there. But here in IA, most of the streams are fairly shorts. 2-3 miles of trout waters is a good guess. There are some few streams that are far from roads or parking lot, those ones are the exception. But generaly 3 to 4 anglers per creek and there is no free place to fish for an extra angler.
When I get the chance to go out of IA to fish, I try to chose places where I can hicke a bit and get some solitude. Last summer I was hicking about 10 miles, go and back through a canyon with a wonderful creek. I had only 1h to fish it, but I managed a dozen of brookies, the biggest was just 10' but, what a beatiful place and wonderful fishing!
